3 • Alky Methanol/Ethanol Additive
Specifically designed for use with ethanol and
methanol fuels. Reduces corrosive properties of the
fuels and reduces bore wash. Also causes Methanol to
burn with a yellow flame, increasing safety in the event
of a fire, with such an additive now being mandatory
for methanol fuelled cars in many MSUK Speed events.
One 222ml bottle treats a 205-litre drum of methanol.

5 • Silkolene Pro Boost
Octane Booster
4 • Torco Unleaded
Accelerator
Torco’s Unleaded Accelerator is race
fuel concentrate. While possessing
many of the same additives as full
race fuel, Unleaded Accelerator
uses a blend of components that
will transform regular fuel from
the pump to closely resemble race
fuel. It also reduces the end burn
temperature which enables fuel to
burn more effectively thus provided
better combustion and ultimately
more power from the engine. Used
at a ratio 20:1 it will provide a rating
of 105 from regular unleaded.
945ml
(F500010TE) £30.15
A high performance octane improver
that is also designed to prevent
pre-ignition or “knocking”. Due to
its’ unique lead-free formula, Pro
Boost enhances combustion, reduces
upper cylinder wear and burns
cleanly without leaving deposits in
the combustion chamber. Throttle
response is improved and helps to
reduce heavy exhaust gas pollution
when the engine is cold. Pro Boost
is also compatible with all forms of
petrol and does not harm fuel hoses
or filters. Available in a 1 litre bottle,
mix at 1-3% of the total fuel for the
best results.
1 Litre
(602014818) £21.50
Now endorsed by the Federation
of British Historic Vehicle Clubs
(FBHVC) as a fuel additive for
protection against corrosion in
metals. Essential for nearly all pre
1996 engines. It quickly removes
existing gums, varnishes and carbon
deposits and protects against
them building up again. Ethomix
fuel additive is compatible with 2
or 4 stroke petrol engines and can
improve performance and reduce
emissions. Ethomix also stabilises
ethanol in fuels so rubber lines and
seals will not degrade. 250ml bottle
treats 250 litres of fuel.
